OS/Filesystem for file server ~ 8Tb

Standard availability is likely all you need, which I completely understand. Its the base that any business really does need.
But spending for software, that you're unable to use or scale up as needed is painful.

@Doyler3000 said in OS/Filesystem for file server ~ 8Tb:
I get the centralised management, plus the agentless backup. And it's quite a bit cheaper than essentials plus as I remember. High availabilty is not a major concern for us.
So why spend the money on a hypervisor when all major hypervisors are provided for free?

Without wanting to draw out the virtualisation platform questions anymore let me just say that the £600 or something we paid for essentials is not outrageous given that it's the platform
- I'm most familar with and
- the people in the company who would have to step in if I wasn't around are most familiar with
I completely accept that Xenserver and it's bells and whistles come for free and I'll definitely take it into consideration when I'm implementing a solution.
Now onto the filesystem and OS for the VM

!XenServer with Xen Orchestra, use CentOS for the VM.
All linux, all day, and save that £600 for Beer-Friday!

£600 will keep me in beer for quite a while. I don't drink like I used to
So with Centos as the VM, would you use LVM snapshotting? ZFS on linux and BTRFS are not quite production ready seems to be a common (possibly wrong) consensus. There would be complaints if we lost the file system snapshotting that ZFS allows.

LVM will do snapshots at the filesystem level yes.

Use CentOS as the server, use Veeam for your backups. You get a bit more functionality with it, especially if you aren't familiar with the process to restore files using the backed in snapshot functionality.
-
Yes I'd keep using Veeam for backups. I'd class the snapshotting and backups as different functions really. I'd be hoping to use the snapshots for restoring single files or directories, the backups more for restoring the file server in a disaster.

@DustinB3403 said in OS/Filesystem for file server ~ 8Tb:
With Essentials do you get the ability to backup your VM's without an agent? Or really any other benefit?
I thought it was Essentials Plus.
With Essentials, isn't that just to allow for more cores and memory?
Essentials Plus gives you HA and support. Essentials is no support, and all you get are backups.
-
@Doyler3000 said in OS/Filesystem for file server ~ 8Tb:
and yes it's snapshotting at the file level I'd need to replicate the daily zfs snapshots we've got now.
Why replicate here rather than with Veeam? Veeam does this well. Are you using ZFS' internal syncing protocol?

That can make sense. Although I'd consider re-evaluating your Veeam usage instead. Veeam will do this in a single place, more powerfully than doing snaps inside the VM will.
This is really Veeam's strong suite.

They are both production ready, but the big question is always... why look for niche solutions when the mature, normal ones are SO good at it? LVM and XFS are the mature choice for this for two decades.
ZFS has always been considered silly on Linux because snapshotting was always there, since the 1990s. ZFS doesn't offer new functionality there. It was new on Solaris, either. Solaris had snaps in the 1990s as well. Long before they added ZFS.

That's a very unhealthy way of looking at it. What you should ask is "what did you get for that money?" And the answer is "screwed."
In absolute terms, £600 is nothing for any viable business to spend. So it sounds reasonable when looked at in that way and if it was getting you valuable stuff, then absolutely without question, just spend it.
But we have to work in relative terms. For £600 what did you actually get? You got a very limited system without the features you would get for free from any other system, that's it. You are literally getting a negative value out of spending £600.
To put it another way, if ESXi Essentials was free instead of £600... we would still be having this conversation about choosing the only platform out there that doesn't provide a certain base set of features. The £600 is a red herring, it's that ESXi isn't up to snuff here, it's not a viable option. ESXi isn't really a consideration until you are talking about Essentials Plus for much, much more money and mostly that is because you are getting support. It's not that ESXi is bad, it's awesome. But you are getting screwed if you are trying to use it below the Essentials Plus tier.

@Doyler3000 said in OS/Filesystem for file server ~ 8Tb:
We're almost entirely a linux operation here though we have a few windows clients.
Just have to mention that this fact makes ESXi a weird choice as you need a range of skills instead of being able to focus on the ones that you have. If you have Linux skills, you are ready for KVM or Xen
-
CentOS, Fedora, openSuse and Ubuntu are your choices here and are all fine. If you want to use ZFS, honestly I'd probably use Ubuntu.
If I was building from scratch what you want to do here, I'd likely use openSuse with XFS. All of the choices are fine.

Very valid, in a case like that, though, I'd think other factors would step in. Do you feel that if you were gone that you really still have the expertise to maintain any system (you meaning the other people in the company?) I would think that this would either trigger bringing in a backup ITSP that can help you with whatever platform make the most sense for you and solve this issue entirely. Or bring in someone like @Scale HC3 where the platform is all self managing and they are there to support anything that you need so that you need no expertise or knowledge of it at all. Or both, of course.

@Doyler3000 xfs+lvm or zfs. In any case consider an hba and passthru disks/hba to the vm making soft raid if you can manage it.

Definitely don't do that. Passthrough to a VM is terrible. Very complex and it bypasses loads of the critical abstraction.
-
It would also keep ESXi from being able to use those disks in any way as an additional problem. ESXi can't use software RAID in any form. So no way to even share them.
-
@scottalanmiller I was thinking about a dedicated array not something used by esxi.
Does passthru cause all these issues? I've used it some time ago and it was really nice. Anyway it was not esxi
